The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated vaporizer combusting boiler of the present utility model.
But the utility model vaporizer combusting boiler is the principle that adopts the backfire principle of coal and can change into gas fuel combustion under certain condition, the environment-friendly high-efficiency vertical boiler that designs and manufactures.This vaporizer combusting boiler adopts the chamber combustion technology, has improved the thermal efficiency.
This vaporizer combusting boiler structure is the flue 18 that forms water jacket 6 between boiler foundation 1, shell 19 and the shell.Described flue 18 is divided into three sections of upper, middle and lower: promptly throw coal section, coal-fired gasification section and chamber combustion burning segment, on three sections of the corresponding flue 18 of described shell 1 one sides, be respectively equipped with three air outlets 8 that enter burner hearth through water jacket 6 to flue simultaneously, be provided with the grate water pipe 10 that axially is certain angle of inclination with flue 18 in flue 18 in the pars infrasegmentalis, the angle of inclination is the 5-8 degree.Its two ends mouth of pipe is connected with water jacket, and the soil shifting opening 12 of corresponding furnace bar tube 10 mouths of pipe is housed on furnace bar tube 10 dead ahead shells 19 corresponding positions, near above the furnace bar tube 10 flue internal perisporium is provided with wall with refractory lining, refracto 15, coal is changed into gaseous state and delivered to the bottom burning segment by solid-state, reduced the furnace water cooling degree and be beneficial to fire burns and gas reforming, made aerogenesis, mixing, combustion integrative.Both sides are respectively equipped with many caecum water pipes 24 that are connected with flue and communicate with described water jacket in wall with refractory lining, refracto 15 bottom furnace bar tubes.Water is flowed in pipe can not produce subcooled boiling,, cooled off the coal-fired temperature in top, do not produce the vaporization vapour locking, make it to be difficult for coking, play the effect of good ventilation owing to leak water in the pipe.Caecum water pipe 24 plays the fire grate effect, holds the coal seam, effectively protects the space of bottom burning chamber.
Be provided with delivery port 16 at the boiler top, system's backwater is connected on heat exchanger 22 tops, is provided with many screw thread heat exchanger smoke pipes 23 in the heat exchanger 22, is equipped with in the pipe and scratches flow, and fire, flue gas are upwards flowed through fire tube 3, and water flows downward, and forms the exchange heat of maximum temperature difference.。Be provided with in heat exchanger 22 bottoms communicate with water jacket 6 advance stove return pipe 2, heat exchanger 22 bottoms are connected with water seal dust-removal and desulfurizing groove 21, make dust flow through the effect of washing one's hair of tank dilatation and water and remove, above water seal dust-removal and desulfurizing groove 21, add the liquid desulfurizing agent or in coal cinder, add sulphur-fixing agent and all can.Boiler bottom has sewage draining exit 17, is provided with the fire-resistant concrete 14 of one deck on boiler foundation 1.Fire-resistant concrete 14 increases burning chamber place, bottom temperature, and being beneficial to Lou, slag burns away.
This vaporizer combusting boiler burning structure is: the igniting of water pipe furnace grate top, wall with refractory lining, refracto 15 and on, under the effect of ventilating of the ajutage Final 8 system at middle part, make lump coal (or moulded coal) produce coal gas in combustion gasification indoor seasoning, destructive distillation, decomposition, and deliver to high temperature burning chamber under the fire grate, after ajutage 8 air distributions in bottom fully mixed, the mode of the backfire of burning elimination black smoke, gasification, pressure-fired, chamber combustion made burning fully, release heat is moved not over-emitting black exhaust to greatest extent.
Vaporizer combusting boiler of the present utility model proves through operation: its structure is the mature technology that has adopted bearing boiler, designs the little extreme misery pipe combination water back of the body formula vaporizer combusting boiler of floor space, increases back-end surfaces, makes full use of flue gas heat; The inclination water pipe furnace grate, coal is difficult for coking; Water circulates in the pipe, guarantees to ventilate; Wall with refractory lining, refracto is arranged in the furnace bar tube top, reduces the furnace water cooling degree, strengthens gas reforming; Three sections air-supplies are adjusted reasonable wind distribution according to ature of coal, make catch fire, aerogenesis, burning be more reasonable; After water temperature is set, open, blowing out controls automatically, selects ripe combustion control device for use; Dedusting and desulphurization integrated finishing, efficient, environmental protection, energy-conservation.Weak point is to still have in the short time after the blowing out a small amount of white vapour to emerge.
Adopt the vaporizer combusting boiler to solve the smoke elimination problem
The boiler over-emitting black exhaust mainly be fire coal do not have completing combustion and produce do not burn material, the way of solution is exactly to adopt the technical measures of completing combustion.We adopt the tilting water cooling tube to do grate in design, because tipping tube makes in-pipe flow moving good, do not produce the vaporization vapour locking, add that the water-cooled effect prevents coal-fired coking.Above fire grate, arrange wall with refractory lining, refracto, reduce the furnace water cooling degree and be beneficial to fire burns and gas reforming.The disposable coal amount that fills up after the upper point pyrogene merit produces coal gas (carbon monoxide) and other fugitive constituent under wall with refractory lining, refracto and reverse burning and air-supply acting in conjunction, under the c /v effect, in burning chamber's abundant chamber combustion burning, reach the purpose of smoke elimination.Facts have proved and do not arrange black smoke when boiler normally moves, reach smokeless operation.
Adopt the vaporizer combusting boiler to solve the low problem of the thermal efficiency
Above-mentioned technology solves coal-fired by the solid-state measure that becomes the combustion burning of gaseous state chamber, combustible is burnt cmpletely and emit heat, chemistry, machinery, flying dust imperfect combustion greatly descend, add the reasonable Arrangement radiation heating-surface, convection current is heated and afterbody is heated and the back-end surfaces smoke pipe in install spoiler additional, flue gas flow is strengthened, strengthen and conduct heat, and adopt reverse water inlet measure, reach the reverse exchange of maximum temperature difference, thereby reduce exhaust gas temperature greatly, maximally utilise the coal-fired heat that discharges, boiler jacket, do insulation and handle, reduce radiation loss.Reach the raising boiler thermal output, the purpose of fuel saving.
Adopt the vaporizer combusting boiler to solve grit and sulfur dioxide problem
Under forced ventilation, the soot particle that burns will be removed (or installing cyclone dust collectors additional) down by the dilatation and the water effect of washing one's hair of aft mounted water sealed tank, simultaneously on flue, add desulfurizing agent, make itself and sulfur in smoke chemical reaction (or in coal, mixing into sulphur-fixing agent) and reach the purpose of desulfurization.Water in the tank adds an amount of alkali (soda ash or caustic soda) neutralization back discharging regularly.
Traditional boiler thermal output: about 60%, heating area: 2000M
2, Coal-fired capacity 60KG/H, total coal consumption 86400KG of heating season, day maintenance man-hours 24 hours, season 6400 yuan of working hour expenses, expense amounts to 47872 yuan.The vaporizer combusting boiler thermal efficiency of the present utility model: 82%, heating area: 2000M
2, Coal-fired capacity 30KG/H, total coal consumption 43200KG of heating season, day maintenance man-hours 1 hour, season 1600 yuan of working hour expenses, expense amounts to 22336 yuan.
